Hi,
I tried it with years ago with a (quiet) old version of LS (1.87 or 1.90).
I don't remember exactly the process (using some pathetic html email), only that I was abble to send & receive something.
Here is the end of the good news because what I remember perfectly, was the display of 2 or 3 alerts (during submit) saying that it is unsafe, will harm your computer, form made for hacking etc.
99% of the respondants may give up. I too.

Even a big well know company don't do questionnaire in email.

If the well know company name start with letter 'G' yes they can:

Done! (at sondages.pro)
a) The problem with this kind of survey is that a respondant can probably fill several times the same survey...
b) Could be that it's only working with Gmail or few services more...I don't know
c) Don't be
